Hello,
My prdoucts cutting time is like 15 sec but starting spindle and spindle stop take extra 15 sec. It takes too much time. Is it possible that the spindle non stop working? You can see the start of code and the end of code below. I am using Mach3.In advance I appreciate your helps

What I tried that

1) I remove M30 but not working and code did not come to the begining
2)I put M03 insted of M30 but not working and the code did not come to the begining
3)I put S16000M3 insted of M30 but not working and the code did not come to begining.

M3 starts spindle and M30 turns of the spindle.
